5.3 IMPORTANT CONCRETE AND ANCHORING INFORMATION
1.
Concrete shall have compression strength of at least 3,000 PSI and a minimum thickness of
4”. Measure the length of the supplied anchor bolts in order to achieve a minimum anchor
embedment of 3-1/4”. If the top of the anchor exceeds 2” above the floor grade, you DO NOT
have enough embedment.
2.
Before drilling 3/4” dia. Holes in concrete floor using holes in column base plate as guide, make
sure the hole distance from the edge of the concrete or any cracks is no less than 8”.
3.
DANGER:
DO NOT Install on asphalt or other similar unstable surface. Columns are
supported only by anchoring in floor.
4. Shim each column base until each column is plumb. If one column has to be elevated to match
the plane of the other column, full size base shim plates should be used (Reference Shim Kit).
Torque anchors to
85 ft-lbs
. Shim thickness MUST NOT exceed 1/2”.
5.
If anchors do not tighten to
85 ft-lbs
installation torque, replace concrete under each column
base with a 4’ x 4’ x 12” thick 3,000 PSI minimum concrete pad pinned to the existing concrete
and flush with the top of existing floor. Let concrete cure at least 30 days before installing lifts
and anchors.
5.4 ANCHORING TIP SHEET
1.
Use a concrete hammer drill with a carbide tip, solid drill bit the same diameter as the anchor,
3/4”. (.775 to .787 inches diameter). Do not use excessively worn bits or bits which have been
incorrectly sharpened.
2.
Keep the drill perpendicular to the concrete while drilling.
3.
Let the drill do the work. Do not apply excessive pressure. Lift the drill up and down occasionally
to remove residue to reduce binding.
4.
Drill the hole for anchor bolt completely through the concrete. If an error is made during the
installation of these anchors, this will allow for the anchor bolt to be driven down into the
ground, so that a new anchor may be installed in place (fig.1).
5.
Be sure to clean all dust from hole (fig.
2).
6.
Place a flat washer and hex nut over threaded end of anchor, leaving approximately 1/4 inch of
thread exposed above the nut (fig
.
3). Carefully tap anchor into the concrete until nut and flat
washer are against base plate. Be sure to only tap the top of the anchor and not the nut. This
could cause damage to the threads of the anchor.
7.
Tighten the nut (fig. 4) to
85 ft-lbs
of torque (typically this should only be two to three full turns).
DO NOT USE AN IMPACT WRENCH TO TIGHTEN ANCHORS!
